To make a knife, You need a steel plate. This role is perfectly suited to automotive spring steel grade 5160. The important thing is not to use the material used. Decide to take a spring — take a new one. The length of the plate depends on the length the desired length of the blade for a future knife. A convenient length is 10 inches, but everyone decides for himself. It is important to remember that arm length, needs to be leveled, at least ¾ of the length of the blade.
Based on that, do calculations. Blade, plus ¾ on the handle — get the length of the plate for a knife and not to forget a small "seam allowance".

In addition, You will need a piece of wood The best candidate for this role is oak. It is always safer to buy that part in a joinery shop. So You can be sure that the shaft does not collapse in the hand, and give unexpected cracks.
Also will need a copper rod with a diameter of 0.5 cm. It will be to mount the shaft to the blade. Therefore, the job of his selection so responsibly.
As for tools, to manufacture the knife, you will need a power drill, hacksaw, primitive shelf, a saw, and epoxy.

The manufacturing process is not complicated, but laborious. But You decided to make a knife, so go ahead. On a steel plate with a marker draw the outline of the knife. Draw wider than desired, as the grinding will take its toll. Then the drill make as many holes in this outline. Don't forget to drill and more holes in the future handle. The width of these openings should not significantly exceed the width of the copper rod, keep this in mind when choosing a drill. With the help of a saw "unleash" the knife from the plate. The workpiece should be processed with a hacksaw and a file to remove all irregularities and to smooth the shape.
Next, screw the knife to the rack by the handle and begin to slowly make blade to blade. The blade grind is better a file. This is a basic, the longest and most critical part of the work. Working the blade can take a lot of time, but can't rush it. When the blade is ready, begins the stage of tempering of the knife. The knife should bring the fire to purple. Enough molten metal should not be attracted by the magnet and this is the record for You. After the knife "got" his need to dip into the oil and hold it until the fire goes out and will not disappear in smoke. Then you can cool water.
Once the blade is ready to begin to handle. You need to make a wooden block the two pads made of wood. One need to drive copper rods to lubricate the pad with epoxy, put the knife handle to secure the construction of the second plate is also pre-lubricated with epoxy resin. For the bonding strength, can be put under the press. When a knife feels is ready, it is necessary to clean the ends of copper rods, and treat the cut with sandpaper.
